Step one:
Grab the Custom Shape tool.
Do as the following picture does.
Now press the little arrow. Search for "Banners". If you have done that, you should look trough the pictures you have gotten now. There should be a picture that looks like the one on the final image. But its Black and White. Now set your foreground color to gray.
Open your document, size doesn't actually matter. Pres shift, and keep it pressed in until I say you may stop to do so.
Hold your mouse from one corner to the other one(While clicking xD).. Or in the middle or something. You choose, just make sure it looks good .
*Let Shift go .
Step two:
Now go to Blending Options, and add a Drop Shadow.
Now a Gradient Overlay.
A Stroke..
*Note: I'm not going to name any color. You should take the color that looks good for you.
Step three:
Take out your gradient tool, select the gradient that goes from white to transparent. Take the selection from your tag by Ctrl + Clicking on the picture you see on the Layers pallet. Then you should drag the selection up. After that, add the gradient.
Now add your text, and done!
So sorry for the low quality pictures.
